Maybe in the next few years it will be legal in the entire U.S.! (Hopefully, but maybe I'm dreaming! LOL!) If that comes to be, you can land on the east coast & party your way across country to the west coast & take me with you!
---- In the mean time, I hope someone can answer your original question for you. If you can find 'coffee houses' where you're planning to go, it would certainly make a very memorable vacation (oops! Or maybe not!)
